R/W Description
R0/W1 Flush unit. When set, this event will immediately stop the current
operation and return the unit to idle state.
R/W UART hardware flow enable. Selects use of hardware flow control
with RTS and CTS pins
0 Flow control disabled
1 Flow control enabled
R/W UART data bit 9 contents. This value is used 9 bit transfer is
enabled. When parity is disabled, the value written to D9 is
transmitted as the bit 9 when 9 bit data is enabled.
If parity is enabled then this bit sets the parity level as follows.
0 Odd parity
1 Even parity
R/W UART 9-bit data enable. When this bit is 1, data is 9 bits and the
content of data bit 9 is given by D9 and PARITY.
0 8 bits transfer
1 9 bits transfer
R/W UART parity enable.
0 Parity disabled
1 Parity enabled
R/W UART number of stop bits. Selects the number of stop bits to
transmit
0 1 stop bit
1 2 stop bits
R/W UART stop bit level
0 Low stop bit
1 High stop bit
R/W UART start bit level. The polarity of the idle line is assumed the
opposite of the selected start bit level.
0 Low start bit
1 High start bit
